.net core源碼調試前的配置

一直想想研究.net core的源碼，參照 solenovex大牛的方法，最后終於成功啟動了.net core源碼，過程如下：

1、powershell定位到 X:\aspnetcore\eng\scripts，運行其中的InstallVisualStudio.ps1，在彈出的VS修改安裝界面后，直接點修改，安裝完成后關閉即可。

2、cmd定位到X:\aspnetcore目錄下，運行restore.cmd，此時會下載一個目錄X:\aspnetcore\.dotnet，關閉cmd窗口停止restore進程，編輯目錄下的dotnet-install.ps1文件，

把

Say "Downloading link: $DownloadLink"
try {
DownloadFile -Source $DownloadLink -OutPath $ZipPath

修改成

Say "Downloading link: $DownloadLink,$ZipPath"
try {
while(![System.IO.File]::Exists($ZipPath)){
Start-Sleep -s 5
}
Say "$ZipPath is has exists"
# DownloadFile -Source $DownloadLink -OutPath $ZipPath

作出上面修改的原因是，powershell可能是單線程下載或網絡原因（你懂的），

DownloadFile -Source $DownloadLink -OutPath $ZipPath 這句話是下載安裝包 ，我們注釋掉它，不讓它下載，

Say "Downloading link: $DownloadLink,$ZipPath" 中的$DownloadLink是遠程下載地址，$ZipPath是臨時文件路徑，知道了這兩個地址后用循環判斷，如果文件不存在就休眠5秒，這時我們可以用多線程下載工具或瀏覽器下載遠程地址的文件，下載完成后復制到臨時目錄改成$ZipPath的臨時文件名，然后線程就會解壓文件進行安裝，這樣就不用等很久才能下載安裝包。

3、restore有可能會有些文件沒下載會，也可以在cmd下執行build.cmd命令，估計作用和restore.cmd是一樣的。

4、成功后還要修改D:\aspnetcore\src\Components\Server\src\Microsoft.AspNetCore.Components.Server.csproj  具體問題看 https://github.com/dotnet/aspnetcore/pull/18713/files/9142fbf5940c4c8cd8cc66f50fe63569f50747e0#diff-8d3e3b66d47490ce28ba798996aea5ec

修改成如下內容，對照修改下面綠色粗體內容

5、這時可以打開 其中的源碼解決方案，比如 X:\aspnetcore\src\Mvc ，雙擊這個目錄下的startvs.cmd ，會調用VS打開 MVC.sln並還原依賴的包，直接打開MVC.sln好像無法加載項目，我以后再試。

6、如果正常打開項目，可以試着生成解決方案，如果生成成功，那么調試就沒問題了。默認是test目錄下的BasicWebSite項目為啟動項目的，你也可以修改其它項目為啟動項目。

7、.net core源碼調試成功，記下解決經歷以備忘也可以幫助到其他的人。
